Sun Pointing

What is Sun Pointing?

Sun Pointing meaning Alignment of the radar antenna by locating the position of the sun in the sky, which has an exactly known position given the radar’s location and the present time. This may be necessary to verify that when we think we’re pointing “north”, we actually are! The sun’s signal is usually several dB above the background noise, and this technique is also sometimes used to examine the receiver sensitivity.
